A/C disconnect

I have a situation where I need to change the A/C disconnect to a subpanel, so I can run a few circuits off of the feed. Does the NEC specify that the A/C disconnect need to be fused, or can it be a breaker? Basically, I want to take the fused disconnect out, wire up a 6 space panel and have the A/C directly connected to a breaker in the panel. The feed to the disconnect is a 60a breaker off of the main panel. I believe the condenser unit is 30a.

You'd have to look on the a/c's dataplate. Some say maximum fuse or breaker size, and others just say maximum fuse size. If it just says maximum fuse size, then you're stuck with using fuses in some manner. That doesn't mean you can't set your sub anyhow and feed out to a fused disco for the a/c.
